Abstract: A method of operating a vehicle powertrain includes determining a selected powertrain operational mode. A demand fraction is determined. An internal combustion engine (ICE) is to output a maximum power when a gaseous fuel is conveyed to an injector of the ICE at a source pressure greater than a cutoff pressure. The source pressure in a container in fluid connection with the injector is determined. The gaseous fuel is received at the source pressure by the injector to inject the gaseous fuel into the ICE for combustion in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a first set of criteria. The injector is prevented from injecting the gaseous fuel into the ICE and the powertrain is driven from an alternative power source in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a second set of criteria.

Abstract: A method for increasing capacity of a natural gas (NG) tank. The method includes selecting a container with a service pressure rating of about 3,000 or 3,600 psi. An NG adsorbent is in the container. The container has a maximum fill capacity. The method further includes cooling the adsorbent by Joule-Thomson cooling during filling of the container with NG from a filling source at greater than 3,600 psi. The container is filled to the maximum fill capacity at a fill rate to prevent a bulk temperature of the adsorbent from rising more than about 5° C. above an ambient temperature. A rate of heat transfer from the tank is less than a rate of heating from compression of the NG and adsorption during the filling. The NG adsorbent adsorbs a higher amount of NG than it would at higher than 5° C. above ambient.
Abstract translation: 一种提高天然气（NG）罐容量的方法。 该方法包括选择服务压力等级为约3,000或3.600psi的容器。 NG吸附剂在容器中。 容器具有最大填充能力。 该方法还包括通过焦耳汤姆森（Joule-Thomson）冷却来冷却吸附剂，该容器在填充来自填充源的大于3600psi的NG中。 以填充速率将容器填充到最大填充容量，以防止吸附剂的体积温度比环境温度上升超过约5℃。 来自罐的热传递速率小于在加压期间NG的压缩和吸附的加热速率。 NG吸附剂吸附高于环境温度高于5℃的较高量的NG。

Abstract: A porous carbon material includes a hierarchical porous structure including a primary microporous structure and at least one of a secondary mesoporous structure and a secondary macroporous structure. The porous carbon material is formed by combining a halogenated-hydrocarbon, an aprotic hydrocarbon solvent, and a reductant to initiate a reaction that forms intermediate particles having a microporous framework; and subjecting the intermediate particles to a heat treatment at a heat treatment temperature ranging from about 300° C. to less than 1,500° C. for a heat treatment time period ranging from about 20 minutes to about 10 hours to thereby form the porous carbon material. The aprotic hydrocarbon solvent is selected from the group consisting of toluene, hexane, cyclohexane, and combinations thereof.

Abstract: A method of making a metal organic framework (MOF)-polymer composite material includes forming a homogeneous solution comprising a solvent, a metal salt, a polymer which is soluble in the solvent, and a reactant which can be synthesized to provide an organic linker during formation of a MOF structure, synthesizing the homogeneous solution to crystallize a MOF structure in the homogenous solution to yield the MOF structure distributed in a remainder solution, applying an antisolvent to the remainder solution with the MOF structure distributed in the remainder solution to form a polymer-rich phase, where the MOF structure is integrated into the polymer matrix during forming of the polymer matrix to produce a MOF-polymer composite material. The MOF-polymer composite material can be formed on a substrate to produce a MOF structured object, which can be a membrane, film, or other object.
